Superior quality, precocity, and competitiveness

This screening test is done by taking a simple and unique blood sample, and is based on the serum markers: hormones produced by the fetus or the placenta, passing into the mother’s blood flow during pregnancy. After the blood sample is taken, between the 11th and 13th week of pregnancy, the analysis allows us to assess the risk of the main trisomies (21, 18, …) for the fetus. The risk calculation is made by combining the age of the patient, the nuchal translucency measure taken at the first semester, and the 4-hormone analysis during the first semester. Prenato has introduced the first quadtest in Quebec: by multiplying the number of hormones analyzed in the first test, we raise the efficiency of the Premium Prenato Screening.

Noninvasive prenatal testing (NIPT)is a newer, more advanced screening option which uses cell-free DNA in a pregnant mother’s blood to test for certain chromosome conditions in her pregnancy, without the risks associated with invasive procedures, such as amniocentesis or chorionic villus sampling (CVS).


This test can be performed as early as 10 weeks’ gestation, with results available in 3-5 business days.
